Summary: There's a learning curve but once you get it, it all makes sense. Great looking screen and the unit itself is really nice. The battery doesn't last very long. Maybe 20 minutes. It takes awhile to get a GPS signal, sometimes 5 to 20 minutes but I think an external antenna would make that better. Overall, I like this GPS Unit. I hope you find this review helpful.
Summary: I've had one for a while now. They were made in 2007 and there were never any map updates. V7 has not supported the Nav740 for a few years now, and the battery shows it's age as well. The battery was never very good and only lasted about 20min when new, but I just keep mine plugged into the car all the time anyway. The voice is ok, but I usually keep mine on mute. The media player is a bit out dated, but I think there is a way to load in a 3rd party player.
